CAN-bus + arduino, how is work?

How do I display CAN data to my 2.8 inch TFT display with touch (Velleman ILI9341)?

Step 1: Put the 2.8 inch TFT display with touch (Velleman ILI9341) in a box. Mail the box to a friend.
Step 2: Get the CAN bus shield/communication working.
Step 3: Have your friend send the 2.8 inch TFT display with touch (Velleman ILI9341) back to you.

Do NOT try to get 47 things working at the same time. DO try to get ONE thing at time working.
